Moonjack - Smart Contract Audit Report
Summary
Moonjack is a new Defi token on the Binance Smart Chain with the objective of sending their mascot, a flapjack octopus, to the moon by use of an autonomous yield and liquidity generating protocol.
Overview of the Contract:Audit Findings Summary
- The total supply of the token is set to one quadrillion.
- No mint or burn functions are present; though the circulating supply can be reduced by sending tokens to the 0x..dead address, if desired.
- As of the date of this report, roughly 30% of the token's supply has been sent to the 0xdead address.
- At the time of writing this report, about 20% of the total supply is in liquidity
- 88% of that liquidity is locked in an unverified contract.
- 12% of liquidity is permanently locked in the token contract.
- 5% of the supply is locked with BSCrypt, however, that same 5% is currently unlocked as the locked duration has passed. We recommend that the team relocks these tokens.
- The team holds 5% of the supply unlocked in a team wallet.
- The next largest holder has 2.5% of the total supply.
- Moonjack's code implements and builds upon the fee-redistribution features pioneered by Reflect Finance.
- Users who hold tokens will automatically receive a portion the fees from a transaction tax on each transfer.
- A portion of the fee charged on transactions is stored in the contract and, once a threshold value is met, used to fund PancakeSwap liqudity.
- Liquidity-adds are funded by selling half of the tokens collected as fees, pairing the received BNB with the token, and adding it as liquidity to the BNB pair.
- The LP tokens received from this process will be permanently locked in the contract.
- The owner of the contract can exclude and include users from transfer fees, update the maximum transaction amount, update the fee percentages to any amount at any time.
- Some functions could have been declared external instead of public to save some gas, but as this is already deployed this is merely informational.
- The contract utilizes SafeMath libraries to prevent overflows along with following the BEP20 standard.
- No security issues were identified in our analysis.
- Further, ensure trust in the team as they have substantial control in the ecosystem. We advise that the team renounces ownership.
